Abstract

Prof Osamu Ishitani

Both the problems of the global warming and shortage of the fossil fuels have brought about great interest in photochemical utilization of CO2 with solar energy.   Efficient photocatalysts for CO2 reduction must be necessary for development of such an important technology.

We have developed novel types of photocatalytic systems using metal complexes and/or semiconductors as a photocatalyst.1   In this presentation, I will focus on the architecture of two types of the photocatalysts using transition metal complexes:

(1) A mixed photocatalytic system including a ring-shaped Re(I) multinuclear complex as a photosensitizer2

(2) Ru(II)-Re(I) and Ru(II)-Re(I) supramolecular photocatalysts.3

The efficiency of the former photocatalytic system has been highest in the reported CO2-reduction photocatalysts ( = 82%), and the latter photocatalysts have been most robust (TON > 3000).
